the Very Edge of the Glacier
Many of the glaciers in Alaska are retreating. Whether due to normal cycles of hot and cold temperatures or to global warming is a much discussed controversy. This particular glacier used to end in a lake, but it has, for the time being, retreated up the valley leaving piles of fine glacier flower and sand in the form of a complex of glacial moraines. It was interesting to find out that the ice from the glacier was still under the piles of sediment. We got to walk right up to the ice and I will have further photos in this particular series in the future.
